LM5168 evaluation module 115-V fly-buck regulator


Order now


The LM5168FEVM evaluation module (EVM) is a fully assembled and tested circuit for evaluating the LM5168, a 115-V DC/DC fly-buck regulator that employs synchronous rectification to achieve high conversion efficiency in a small footprint. The EVM operates over a wide input voltage range of 20 V to 115 V (120-V absolute maximum) to provide a regulated 10-V output at up to 0.25 A with a 750-kHz switching frequency. An additional 10-V floating output is provided through the fly-buck topology. The output voltage has better than 1.5% set-point accuracy and is adjustable using an external resistor divider. The module design uses the LM5168-Q1 synchronous buck converter with wide input voltage range, wide duty-cycle range, integrated high-side and low-side power MOSFETs, advanced overcurrent protection, and precision enable.

  • Integrated synchronous rectification
  • Low operating quiescent current
  • High efficiency at light loads
  • Low minimum on-time
